head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Optimization · Pure Optimization
Engineering precise gas, liquid, and power circuits to keep a subterranean colony alive indefinitely.

Optimization · Pure Optimization
A Pathfinder system-mastery game where feat optimization and kingdom timeline routing determine survival.
Oxygen Not Included leans Optimization (Pure Optimization); Pathfinder: Kingmaker leans Optimization (Pure Optimization).
Pathfinder: Kingmaker leans a little harder on execution, though the gap is small.
Oxygen Not Included
All inputs are build-order clicks; no twitch required
Pathfinder: Kingmaker
Real-time-with-pause removes twitch; timed kingdom events add pressure marginally
Pathfinder: Kingmaker leans a little harder on reads, though the gap is small.
Oxygen Not Included
No adversary of any kind exists in the colony
Pathfinder: Kingmaker
All enemies and advisors follow scripted patterns without player modelling
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Oxygen Not Included
Asteroid seed and geyser placement carry meaningful but bounded randomness
Pathfinder: Kingmaker
Hidden ability check thresholds and timed kingdom deadlines create unknowns
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Oxygen Not Included
Gas, liquid, and power engineering are essentially a solvable engineering puzzle
Pathfinder: Kingmaker
Pathfinder feat chains and kingdom management routing have known optimal solutions
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
